__How you can help: __ "While you can never say never (who wants an empty promise?), let your boyfriend know that you would never want to cheat on him. Clearly state your priorities, including loyalty and fidelity," says Stacey Rosenfeld, Ph.D., a New York City clinical psychologist. "Reassure him that you're interested in only him and that if things got rocky in the relationship, you'd articulate your concerns rather than acting out on them."
